  • Patent number: 11867251
    Abstract: A pulley decoupler for an accessory drive comprises input and output parts. The output part and the input part are rotatable about a common axis of rotation and are rotatable to a limited extent relative to one another. A centrifugal pendulum device is provided for damping torsional vibrations with a centrifugal pendulum flange that can be rotated about the axis of rotation and has at least one pendulum mass displaceable under centrifugal force relative to the centrifugal pendulum flange. The at least one pendulum mass is acted on by a friction force generated by a first friction device having a first spring and at least one first friction element.

  • Patent number: 11287024
    Abstract: A pulley decoupler for a drive train of a motor vehicle is disclosed for eliminating or reducing rotation-related irregularities transmitted by a crankshaft. The pulley decoupler comprises a pulley hub, an arc spring flange, and a torsional vibration damper flange of a torsional vibration damper. In embodiments, the pulley hub, the arc spring flange, and the torsional vibration damper flange are configured to be non-rotatably mounted on a crankshaft by at least one crankshaft screw. The pulley hub has an outer lateral surface region on which both the torsional vibration damper flange and the arc spring flange are received and on which they are configured to be non-rotatably mounted.

  • Patent number: 11162544
    Abstract: A freewheel for blocking or interrupting a torque transmission of a motor vehicle comprises a first ring configured for the input and/or output of a torque and a second ring that is arranged substantially coaxially to the first ring and configured for the output and/or input of the torque. The freewheel includes a plurality of first blocking elements, movable between a blocking position and a freewheeling position, for blocking the first ring with the second ring in a circumferential direction in the blocking position and for interrupting a torque transmission between the first ring and the second ring in the freewheeling position. A decoupler is coupled to the second ring or to the first ring for damping rotational irregularities. The decoupler has a housing, mounted on the first ring or the second ring via a housing bearing, for providing a restoring torque directed against the rotational irregularity.
